Procedure

JOB DESCRIPTION & APPLICATION:
Maxfil-81W is an all-position low alloy steel flux cored wire designed for welding of high strength weather-resistant grade steels. The wire gives optimum performance with 100% CO2 shielding and characterized with smooth metal transfer, uniform welding even on vertical-up stringer beads and easy slag removal. In fillet welds, the bead contour is flat to slightly convex with equal leg lengths and uniform sidewall wetting. Weld metal is free from porosity and conforms to X-ray soundness.
Maxfil-81W is designed for single and multi-pass welding of weather resistant steels - Corten steels grade A/B, Class 1 steels of type A of SA-533 etc.
Goods wagons or freight wagons also known as goods carriages, goods trucks, freight carriages or freight trucks are unpowered railway vehicles that are used for the transportation of cargo. A variety of wagon types are in use to handle different types of goods.
BCNA-HSM-1 is a high-speed Bogie covered wagon fitted with air brakes (All welded broad gauge covered wagon), used to carry cement, fertilizer, and food grains. MAXFIL-81W was used for welding of Roof, Bodyside and Body end of the wagon.
IRSM-41 Steel is also called Weathering steel, often referred to by the genericized trademark COR-TEN steel is a group of steel alloys which were developed to eliminate the need for painting and form a stable rust-like appearance after several years' exposure to weather. The original COR-TEN received the standard designation A242 (COR-TEN A) from the ASTM International standards group. Newer ASTM grades are A588 (COR-TEN B) and A606 for thin sheet. All alloys are in common production and use.
